British police on Wednesday said they had charged a 19-year-old man with terrorism and firearms offences.
Alfie Coleman was charged with preparation of terrorist acts, collecting information likely to be useful for terrorism as well as possessing a firearm and ammunition, London's Metropolitan Police said.
Coleman was arrested in east London on Sept. 29. He will appear in court on Thursday.
"Whilst we can't comment on the details of the case now that legal proceedings are active, I want to reassure the public that we do not believe that there is any enduring threat," said Commander Dominic Murphy, who leads the Met's Counter Terrorism Command.
